Sorry for your computer problems. I’ve never owned a PC. My oldest son got me started on Macs many years ago, and I’ve stuck with them ever since. Both my desktop (iMac) and laptop (MacBook Pro) are from 2011. Last year I had to take my laptop in for the first time because of some video problem. They fixed it for a decent price, but I know I’ll be hard-pressed to be able to afford a new Mac when these two $hit the bed. My oldest son uses Linux and Windows now on his own PCs, mainly because his job uses Windows-based computers, so I can’t even ask him anything about Macs anymore. I’m very hesitant to purchase a Windows-based machine. At my age, I don’t know if I want to deal with learning a new OS.
I used to be a PC user, but that all changed about 3 years ago when I went Apple. I love my Apple iMac and my Macbook Pro. Haven't had much in the way of problems, and Apple support is great.
I strongly suggest you check out MacSales.com
Used Macs are very reliable and affordable; buy the best you can afford.
